摘要: This article describes a protocol that details methods for the isolation of yeast nuclei from budding (Saccharomyces cerevisiae) and fission (Schizosaccharomyces pombe), immunogold labelling proteins, visualization by Field Emission Scanning Electron Microscopy (FESEM). involves removal cell wall nucleus within, followed subsequent processing high resolution microscopy. The nuclear step is performed enzymatic treatment cells to rupture generate spheroplasts (cells have partially lost their characteristic shape), centrifugation. has been optimized envelope (NE), pore complexes (NPCs), associated cytoskeletal structures. Samples, once processed FESEM, can be stored under vacuum weeks, allowing considerable time image acquisition.
